Ridge to Nowhere 12 Hour/40 Miler

You know we’re always pushing the envelope of what’s possible through physical and mental endurance, so we proudly offer our first 12 Hour Trident race for 2022! But this is no ordinary 12 Hour race!

Runners will run one 3.3 mile Trident loop every hour from noon to midnight beginning at the top of each hour. Sounds easy so far, right? All runners will have to be back at the starting line before the hour is up or you will be mercifully released from the race.

To make it even more interesting, beginning at 1 p.m., and every other hour after that until 11 p.m. we will eliminate the last runner on the course who comes in under the hour. (All runners coming in AFTER an hour will be automatically eliminated) You know the saying about “you don’t have to be faster than the bear to get away, just faster than the guy next to you” - that applies here. So at 1 p.m., 3 p.m., 5 p.m., 7 p.m., 9 p.m., and 11 p.m., we will eliminate the last runner on the Trident course while everyone else moves to the next hour.

The top male and female competitors will be crowned king and queen of The Ridge - final placements will be a result of the combined times of all 12 hours, so the faster you did your 12 loops, the higher your placement will be.

We will have finishers awards for all finishers of this devious challenge!

You will end up with approximately 40 miles and 2,500-3,000 feet of elevation gain! This race is no joke - temps in late July hover in the mid 90’s with daytime heat indices pushing 110-115 degrees! Sand temps during the afternoon are upwards of 125-130 degrees! This is a fully supported race with ice and goodies every 1.25 miles or less.

Sound too intense? Maybe dip a toe into the summertime madness that is the Trident with a “kinder” offering like our original noon half marathon, our twilight half marathon, or both half marathons, our “Maratón de las Muertes!


We are having a presale for the Ridge to Nowhere primarily to gauge interest, but also to let you put your name on the dotted line early in case it turns into a popular idea. We are still allotted our 80 spots for the entire Trident race, all distances included, so this will help us allocate as many spots as possible for the various distances the Trident has to offer allowing as many runners as we can to race the distances they want. It’s a complicated math formula and if math has taught us anything it’s that math is hard.

When you register for the presale, you WILL NOT be charged. This is just you throwing your name into the hat. Credit card processing is paused until October 31st when general registration opens for the other races - the noon half, the twilight half, and the Maratón de las Muertes. If you register for the presale after (if) it sells out, you’ll be registering for the waitlist.

Presale registrations begin at 6:00 a.m. on Friday, October 1st!

Refund/Deferral Policy

We want you to register with confidence! You may request a full refund, minus the Ultrasignup fee, should you need to drop for any reason, until, Saturday, April 1st, 2023.

If we have to postpone the race due to a hurricane, natural disaster, pandemic, etc…we will defer everyone to the new date once we’ve settled on one. No mass refunds will be issued. Your money over and above what we spend on the race goes toward the PBC Natural Areas Program which helps protect, enhance, and promote Palm Beach County’s hidden gems like Jupiter Ridge!

Run the ancient sand dunes!

Jupiter Ridge Natural Area is one of the last stands of Florida Coastal Scrub habitat in Palm Beach County. Only 2% of original Scrub in the county and less than one-third of the original Scrub in the state remain today. A gently rolling landscape of prickly, dense thickets spotted with bare patches of sparkling white sand, these 271 acres are protected by Palm Beach County as part of a countywide system of natural areas. Over 200 species of plants and animals call this home.

These natural areas are managed by the Palm Beach County Environmental Resources Management team, and we are tremendously fortunate to be working with them to make this race a reality.

The Trident portion of Jupiter Ridge Natural Area is ran on the dunes south of the FPL easement road. These dunes have remained unchanged since the last ice age over 2 million years ago and contain “peaks” that are the highest natural points in Palm Beach County!

Pick Your Poison!

The 5th Annual Trident Trail Race Series returns on Saturday, July 29th, 2023, at HIGH NOON! For our fifth year, we are bringing you 4 races to choose from!

1. Our original Trident Trail Half Marathon that starts at high noon! Same misery, same 4 hour cutoff! It’s the OG race that so many of you love to hate and hate to love!

2. The Trident Twilight Half Marathon! The same version of the day Trident, but it starts at 8 p.m. with a midnight cutoff! This one is going to be a party! A festival of suffering, a party in the scrub! Wear your brightest and most outrageous running attire!

3. The “Pequeña Cresta - the “little ridge” - our newest offering! Think of it as The Ridge to Nowhere’s little sister! Same format, just have a long, half as miserable!

4. The Grandaddy - the truly grueling 12 Hour, 40 mile elimination race, the Ridge to Nowhere! Our inaugural running of this race proved it is one of the toughest and most challenging races in Florida and beyond. With a dismal 35% finishers rate, this one’s not for the weekend warrior. No qualifying races required, but please be aware of what you’re signing up for. This isn’t so much a running race as it is a survival event.

Race Day Details!

- Parking/Shuttle:

Because the public parking lot at Jupiter Ridge Natural Area is small; less than 10 spots, and because it’s about a half mile to the race starting line, we are providing you a shuttle from an off-site parking lot located at Marcinski Road and Ocean Blvd, right next to the beach. This parking lot has restrooms with real toilets and running water; it will be your last opportunity to use real plumbing before the race, should you need/want to.

The shuttle van will be picking up and dropping off approximately every 10 minutes.


You may be dropped off, but your drop-off person must also use off-site parking if they intend on staying for the race. Jupiter Ridge is open for usual business on race day and we want to keep it clear for visitors not affiliated with the race.

We have rented a nice, new, comfortable, air-conditioned van to take you to the race in style. Please take advantage of it. If you park in the Jupiter Ridge lot, you may be asked to move your car. We are not responsible for anyone getting ticketed or towed because they didn’t follow these instructions.

- Bags/Coolers:

Each runner may have 1 (one) small bag or a small cooler to take with them to the race site. You will be provided with sufficient aid at the race, but if you want anything extra, bring it with you. Nothing larger than a standard duffel bag, please.

- Their Rules/Our Rules:

Jupiter Ridge Natural Area is a protected, environmentally sensitive site owned by Palm Beach County, and managed by Palm Beach County Environmental Resources Management. When we are on their property, we must abide by their policies which are as follows:

- no smoking
- no hunting
- no feeding wildlife
- no alcohol
- no discharging firearms
- no pets or domestic animals
- no bicycles or motor vehicles
- no collecting plants or animals

We, as Race Directors, have our own rules, and breaking these will get you disqualified and possibly barred from racing in any of our future events:

- Course cutting/cheating: this one is an automatic disqualification. Zero tolerance. ‘Nuff said.

- Littering: we don’t mean if a Gu wrapper accidentally falls out of your pocket. We mean flagrant littering, knowingly discarding of garbage on the trails.

- Damaging environmentally sensitive plants by going off-course, handling of any animals you might encounter during your race. The race takes place entirely on the double-track sugar sand roads and there should be no reason to go wandering off into the bushes. We will have porta-pottys at the start/finish line, so you’ll have sufficient access to toilets during your race.

- Being Rude To Volunteers:

Our volunteers are quite simply the best, and we love them wholeheartedly. These folks are the backbone of our races, some of which will be sacrificing time with their families, or missing work to come and stand in the heat, getting bit repeatedly by horseflies to help you finish your race. They are to be treated like the rock stars they are. Our volunteers are fellow ultrarunners, race directors, and generally positive, high-energy, fun-loving people who want to help you achieve your goals. We don’t condone or accept disrespectful behavior toward them.

The Horrible Half & Full

The race itself, both the day and night version, is an out-and-back "loop" of 3.29 miles repeated 4 times for a distance of 13.1 miles. While it's not an ultra marathon, it is very much an endurance event! This race is held during the hottest, most humid time of the year, with a noon start time for the day Trident, and an 8 p.m. start time for the night Trident. Late July temperatures can peak in the 90's during the middle of the day, and humidity hovers around the 70-80% mark making for a ridiculous heat index topping 110+ degrees! The white sand temperatures blaze to a searing 120+ degrees! Heat management is crucial. This race is not for everyone. The course is made up entirely of ancient sand dunes, some of it very soft and fluffy, with some gentle rollers and some outright steep climbs. This is the only Half Marathon in south Florida that will give you 1,200+ feet of elevation gain over the entire distance. Combine the brutal terrain with the unrelenting heat and humidity, and you're running easily the most challenging trail half marathon in Florida.

There is a strict 4 hour cutoff time for both the day and night events! Day Trident runners must have completed all 4 loops by 4 p.m., or they will be listed as Did Not Finish in their results. Night Trident runners must be finished with all 4 loops by midnight! We will have a “soft cutoff” an hour before each race’s finishing time. Race management reserves the right to remove anyone from the course who displays distress above and beyond "normal and expected" for this type of event. We will have a medical staff on hand who will be evaluating runners as they make their way through the race.

Same rules apply for the night version! You must be on your last lap by 11 p.m. or you will not be permitted to continue. Think the night version will be easier? Think unrelenting mosquitoes and 100% humidity!


As this race is brought to you by the same folks who brought you the Sand Spur, you can expect the same level of goodies and bling, including amazing finishers medals, shirts, stickers, and other goodies! You'll also be escorted to and from the race site to a nearby public parking area in an air conditioned van. We'll also have custom top finishers awards for the top male and female winners. Aid stations will be stocked with plenty of ice, water, liquid fuel, chilled fruit, and other goodies! The race will be professionally and accurately timed by our friends Justin and Jill at Trailhead Ultras and results will be posted to Ultrasignup shortly after the race.
